A method for a terminal receiving a guaranteed time slot (GTS) allocation in a wireless personal area network (WPAN), according to one embodiment in the present specification, comprises the steps of: deciding a GTS allocation interval based on characteristic information of the terminal; and transmitting a GTS request to a WPAN coordinator, wherein the GTS request comprises the GTS allocation interval which is decided by the terminal; and receiving the GTS allocation information from the WPAN coordinator, wherein the GTS allocation information comprises the GTS allocation interval which is decided by the WPAN coordinator based on the GTS request that is transmitted by the terminal.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method of receiving a guaranteed time slot (GTS) allocation by a device in a Wireless Personal Area Network (WPAN) system, comprising: deciding a GTS allocation period based upon characteristics information of the device; transmitting a GTS request to a WPAN coordinator, the GTS request including: a GTS allocation period decided by the device; and a GTS period field having a length of 2 bits, the GTS period field indicating the GTS allocation period decided by the device; and receiving GTS allocation information from the WPAN coordinator, the GTS allocation information including a GTS allocation period decided by the WPAN coordinator based upon the GTS request transmitted by the device.
2. The method of claim 1 , wherein the GTS allocation information is received via a beacon frame.
3. The method of claim 2 , wherein: the beacon frame includes a Start Sequence Number field having a length of 6 bits and a GTS period field having a length of 2 bits; the Start Sequence Number field indicates a sequence number of a superframe from which GTS allocation to the device starts; and the GTS period field indicates the GTS allocation period decided by the WPAN coordinator.
4. The method of claim 1 , wherein the GTS allocation information is received via a GTS confirmation command.
5. The method of claim 4 , wherein: the GTS confirmation command includes a Start Sequence Number field and a GTS period field; the Start Sequence Number field indicates a sequence number of a superframe from which GTS allocation to the device starts; and the GTS period field indicates the GTS allocation period decided by the WPAN coordinator.
6. The method of claim 4 , wherein, after the receiving of the GTS allocation information, the device operates in a sleep mode up to a superframe including a GTS decided by the WPAN coordinator.
7. A device configured to operate in a Wireless Personal Area Network (WPAN) system, comprising: a radio frequency unit configured to transmit and receive signals; and a controller connected to the radio frequency unit, the controller being configured to: decide a guaranteed time slot (GTS) allocation period based upon characteristics information of the device; control the radio frequency unit to transmit a GTS request to a WPAN coordinator, the GTS request including: a GTS allocation period decided by the device; and a GTS period field having a length of 2 bits, the GTS period field indicating the GTS allocation period decided by the device; and control the radio frequency unit to receive GTS allocation information from the WPAN coordinator, the GTS allocation information including a GTS allocation period decided by the WPAN coordinator based upon the GTS request transmitted by the device.
8. The device of claim 7 , wherein the GTS allocation information is received via a beacon frame.
9. The device of claim 8 , wherein: the beacon frame includes a Start Sequence Number field having a length of 6 bits and a GTS period field having a length of 2 bits; the Start Sequence Number field indicates a sequence number of a superframe from which GTS allocation to the device starts; and the GTS period field indicates the GTS allocation period decided by the WPAN coordinator.
10. The device of claim 7 , wherein the GTS allocation information is received via a GTS confirmation command.
11. The device of claim 10 , wherein: the GTS confirmation command includes a Start Sequence Number field and a GTS period field; wherein the Start Sequence Number field indicates a sequence number of a superframe from which GTS allocation to the device starts; and wherein the GTS period field indicates the GTS allocation period decided by the WPAN coordinator.
12. The device of claim 10 , wherein, after the receiving of the GTS allocation information, the controller is further configured to operate in a sleep mode up to a superframe including a GTS decided by the WPAN coordinator.
